The Oakley Flight Tracker XM is all mountain, high performance snow goggle that was designed to give you big goggle vision in a medium fit frame. From cruising groomers to ripping through trees, clarity and field of view are necessary to ensure you have a good day on the hill. This all new goggle was inspired by the Oakley Canopy Goggle, one of the first truly oversized snow goggles. The Flight Tracker XM has a low-profile frame design that provides optimized field-of-view in all directions and allows for seamless helmet integration as well. The triple-layer face foam gives the wearer all day comfort and provides moisture wicking with a polar fleece lining. These are goggles built to offer awesome mountain vision and unparalleled clarity. Thanks to the Prizm Lens Tech it's very easy to read the snow conditions during your descent and see contrast in a wide variety of light conditions.
